Patients with aortic stenosis have loss of large VWF multimers due to high shear stress, which is referred to as Heyde syndrome.50 The Heyde syndrome is similar to type 2a VWD, where there is a loss of VWF function and poor platelet adhesion to collagen.

The acquisition time for cryoprecipitate (3040 minutes) is considerably longer compared to fibrinogen concentrate because of the need to thaw cryoprecipitate. In a recent economic analysis that accounted for cryoprecipitate wastage, it was estimated that the cost of fibrinogen concentrate would need to decrease by around 40% to be competitive with cryoprecipitate in the United States.45, Another important limitation of fibrinogen concentrate is that its use in acquired hypofibrinogenemia is off-label in the United States. 0000008132 00000 n Transfusion. 2005; 19:459467.

Direct oral anticoagulation agents have a different mechanism of action: apixaban and rivaroxabanare inhibitors of factor Xa, and dabigatran inhibits thrombin. Although the direct acquisition cost for fibrinogen concentrate is higher in the United States, this type of analysis does not take into account the cost associated with pathogen transmission.45 It is important to note that as Europe withdrew cryoprecipitate from its markets 15 years ago, it has not reversed course based on the new information. However, the small difference in a chest tube output observed in this study may not be clinically significant.42 The limitations of this small, single-center trial were that 6 patients (10%) in the control group were given fibrinogen concentrate postoperatively, confounding the studys results, and the chest tube output is well known to have limitations as a surrogate for bleeding.

Lyophilized, pooled fibrinogen concentrate has emerged as an alternative source of fibrinogen for the cardiac surgical patients with acquired hypofibrinogenemia. 31. The authors found that 67.2% of patients in the treatment arm avoided any allogeneic transfusion (primary outcome) compared to 44.8% in the control group (odds ratio [OR], 0.40; 95% confidence interval [CI], 0.19-0.84). Low levels of factor XIII are associated with increased postoperative bleeding and reoperation for bleeding in the cardiac surgery.55 Factor XIII administration was previously found to reduce blood loss in the CABG patients, when given at a dose of 1250 or 2500 IU.56 Unfortunately, these results were not replicated in a larger study of cardiac surgical patients, where 17.5 and 35 IU/kg doses were administered, and there was no reduction in allogeneic transfusion or reoperation.57 Nevertheless, in patients with excessive hemodilution or in those with major blood loss, the additional factor XIII activity that is present in the cryoprecipitate may be beneficial in achieving hemostasis. 62.
